Web) is used to find the Darcy friction factor (f) for the sections of pipe. The value for h L is obtained by diving the pressure drops across the sections of pipe by the product of the density (kg/m3) of the fluid and gravity (m/s2). Using equation 2 below and known values, the friction faction can be calculated.
